38188, 5.3% no-calls

I got my family finder results back last Thursday and ran my results through the gedmatch diagnostic test today and I have 38188, no calls:


No-calls = 38188 = 5.3755554961212 percent.

This kit has an unusually high number of no-calls, which usually results in a larger number of false matches.


What should I do? Buy another family finder kit to do a retest or should I go with another testing company to see how the results compare?

Problems with downloading to GEDmatch for FTDNA samples?

I realise that I have the same problem!
I was downloading to GEDmatch in January but realised today that there are too many no-calls. I deleted my kit and downloaded it again but I still have the same problem as you.The same number of no calls for the new download.
This was my message from the diagnostics report for the new kit.
Number of SNPs utilized by GEDmatch template = 710401
Number of regular SNPs = 680701
Heterozygosity index = 0.27766852805669 (fraction of total SNPs that are heterozygous)

No-calls = 29700 = 4.1807373581963 percent.

This kit has an unusually high number of no-calls, which usually results in a larger number of false matches.

I hope someone can help with this.
Regards Louis

5 percent is definitely an unusually high fraction of no-calls. I am surprised that FTDNA will release such results. I would have expected them to rerun the sample. You should call FTDNA to see if they would be willing to rerun the sample in hopes of achieving a more acceptable level of no-calls.
